Thought I'd post this for anyone else that might be attempting this fight...

For some reason, people with the Fenrir key item couldn't trigger the fight, we ended up in Moonlit Path by accident. So we tried exiting but got stuck, relogged then stuck in the area with no BCNM icon. Then we tried talking to the portal, people with the Fenrir Key Item had the only option of Moonlit Path, thankfully someone in the group didn't have the key item and they were able to select Moon Reading. It was confusing because we were still in the arena but thankfully the mobs loaded in and we got the BCNM icon (all while still in the arena!).

Straight forward fight, all cardigans easy to sleep, bind, gravity and silence. We had WHM BLM NIN SAM and had no issues. After phase 1 we didn't get a cutscene and Ajido didn't load in for some people. Apparently he doesn't do anything so you don't have to worry about keeping him alive. All the cutscenes seem to load slow and you end up with a black screen for a couple of minutes. The only black screen we had to logout for was after the end credits for the rank missions, didn't get to see the rank 10 fanfare .

Hope this helps others.

I'm surprised it was so easy. Sandy 10 is brutal. There's like 8-10 mobs and they all have a shitload of HP.

Sucks about the key item glitch. I believe everyone in my 4 man has the key item so we might be stuck without an extra person.

I'd still give it a try, maybe we glitched it somehow >_<. I was honestly disappointed by how easy the fight was. I enjoy a challenge.

Id say its a gift to windy for not having rank 10 for so long. Maybe in a few months it will get patched to be a harder fight.

My 4 man did it with relative ease. All of us had the Fenrir key item too, so maybe what OP experienced was an off chance kind of thing.

There was a hiccup after the second cut scene before the second phase of the fight. We were just waiting for the 2 mobs to spawn for... idk, 15-30s. When they did, it felt like it was out of nowhere, so keep your guard up after the cardians are wiped.
